"Gold Tranche" (Reserve Tranche) refers to
Explanation
The Gold Tranche (now Reserve Tranche) is a portion of a member country's quota with the International Monetary Fund (IMF) that can be accessed automatically without conditions or service fees. While the World Bank (Option A) provides long-term development loans, the IMF focuses on short-term balance of payments support through its quota system, making the World Bank an incorrect choice. This question tests the core concept of the IMF’s resource structure and the specific liquidity facilities available to its member nations.
